tl; dr- What setting do I need to be able to control the volume of the soundbar in the HomeKit regardless of the audio source? New to HomeKit and having trouble understanding how all the pieces fit together in the home theater space. There doesn't seem to be any sound bars that are specifically enabled in HomeKit. AirPlay 2 seems to be the closest analog. I understand that I can control the volume of an AirPlay 2 target, but only if it is actively streaming audio through AirPlay 2. So if I would like to use my HomePod to adjust the volume of the soundbar while, for example, playing Switch My man, I couldn't do that. ** Is there a solution that allows me to automate this? ** I wonder if getting a sound bar that can be controlled by controlling the TV volume and pairing it with a HomeKit compatible TV would solve my problem. If so, what is the name of that feature? Specifically, here are some things I would like to be able to do in the end: * Turn on the TV, switch to a source, and set an arbitrary volume (say, 40%) on the soundbar, all in one command quick * Increase and decrease the volume of the soundbar via HomeKit * Play audio directly on the soundbar would be fine, but I can live without it (I guess AirPlay 2 might be useful here, but I don't want this if it somehow compromises other things which I want to do)
